본 연구는 집단 갈등에 관한 도구 모델(the Instrumental Model of Group Conflict: Esses, Jackson, & Armstrong, 1998)에 기초하여 가부장적 가정환경과 제로섬 신념 간의 관계를 살펴보고, 가부장적 가정환경과 제로섬 신념의 관계에서 성차별적 인식의 매개효과를 살펴보았다. 또한, 이러한 관계가 성별에 의해 조절되는지도 알아보고, 가부장적 가정환경이 성차별적 인식을 매개로 제로섬 신념에 미치는 영향에서 성별의 조절된 매개효과를 검증하였다. 연구대상자는 이공계 대학생 310명(남자 234명, 여자 76명)으로 이들은 가부장적 가정환경, 성차별적 인식, 제로섬 신념을 측정하는 설문조사에 참여하였다. SPSS Macro Process 프로그램을 이용하여 분석한 결과, 가부장적 가정환경과 제로섬 신념 간의 관계는 성차별적 인식에 의해 완전매개되는 것으로 나타났다. 또한, 가부장적 가정환경과 성차별적 인식의 관계는 성별에 의해 조절되는 것으로 나타났는데, 구체적으로 남성에게서는 가부장적 가정환경이 성차별적 인식에 영향을 주는 것으로 나타났으나, 여성에게서는 이러한 영향이 나타나지 않았다. 마지막으로 남성에게서만 가부장적 가정환경과 제로섬 신념의 관계에서 성차별적 인식의 매개효과가 유의한 것으로 나타났다. 이러한 연구결과는 가부장적 가정환경은 남성의 성차별적 인식을 유발하고, 이러한 성차별적 인식은 제로섬 신념으로 연결될 가능성을 높인다고 볼 수 있다. 즉, 이러한 결과를 통해 남성에게서는 가부장적 가정환경이 성차별적 인식을 통해 제로섬 신념에 영향을 미칠 가능성이 확인되었다고 여겨진다.

Recently, an LWE-based commitment scheme is proposed. Their construction is statistically hiding as well as computationally binding. On the other hand, the construction of related zero-knowledge protocols is left as an open problem. In this paper, we present zero-knowledge protocols with hardness based on the LWE problem. we show how to instantiate efficient zero-knowledge protocols that can be used to prove linear and sum relations among these commitments. In addition, we show how the variant of LWE, spLWE problem, can be used to instantiate efficient zero-knowledge protocols.

We investigate the relation between the vector variable bi-additive functional equation $f(\sum\limits^n_{i=1} xi,\;\sum\limits^n_{i=1} yj)={\sum\limits^n_{i=1}\sum\limits^n_ {j=1}f(x_i,y_j)$ and the multi-variable quadratic functional equation $$g(\sum\limits^n_{i=1}xi)\;+\;\sum\limits_{1{\leq}i<j{\leq}n}\;g(x_i-x_j)=n\sum\limits^n_{i=1}\;g(x_i)$$. Furthermore, we find out the general solution of the above two functional equations.

Let M_p := 2^p - 1 be a Mersenne prime. In this article, we find integers a, b, c, d, e and n satisfying $\sum_{t=0}^{n}\;\({an+b\\ct+d}\)\;=\;M_{p^e}$ given a Mersenne prime number M_p. In order to find a special case that satisfies the above results, we reprove an well-known relation of a certain sum of binomial coefficients and a divisor function.

This study was conducted to analyze the degree of department satisfaction and correlation accordng to nurses's clinical characteristics. Data fors tudy were selected August, 1999. The sample coisted of 512 nurses working in K university hosptal in Seoul. The collected materials have been alyzed by percentage, average, t-test, ANOVA, arson Correlation Coefficiency using SPSS window 8.0 program. The result were as the follows ; 1. Fifty-one percent answered to be satisfactory in current department of work, and nurses who had been experienced the transfer are fifty percent, and nurse specialist is eight point two percent. 2. The order of the degree of department duty satisfaction was mutual action, professinal position, autonomy, assignment desire, relation between the doctor and nurses, wage, administration. 3. The result of the degree of department duty satisfaction according to the age has shown significant differences in administration and assignment desire, and the result of the degree of department duty satisfaction according to the education and religion has shown significant differences in administration, and the result of the degree of department duty satisfaction according to marital status has shown significant differences in wage and administration. 4. The result of the degree of department duty satisfaction according La the position has shown significant differences in administration, assignment desire and the sum of duty satisfaction, and the result of the degree of department duty satisfaction according to the nurse specialist has shown no significant differences in total areas, and the result of the degree of department duty satisfaction according to the transfer has shown significant differences in relation between the doctor and nurses, administration, autonomy and the sum of duty satisfaction. 5. The result of the degree of department duty satisfaction according to the nursing career and present assignment career has shown no significant differences in total areas, and the result of degree of department duty satisfaction according to the present assignment has shown significant differences in relation between doctor and nurses, administration, assignment desire and the sum of duty satisfaction. 6. The result of the degree of department duty satisfaction according to the request and experiences of trasfer has shown significant differences in wage, administration, assignment desire and the sum of duty satisfaction 7. The result of the degree of department duty satisfaction according to the degree of satisfaction of present assignment has shown no significant difference in professional position 8. The result of relation of nurses'a clinical characteristics and the degree of department duty satisfaction and the sum of duty satisfaction has shown no significant differences in age, present assignment career, but the result of nursing career has shown significant differences in relation between doctor and nurse, administration, autonomy, assignment desire and the sum of duty satisfaction. and the satisfaction of present assignment which was very effective on duty satisfaction was as significant correlation with wage, professinal position, relation between doctor and nurses, administration, autonomy assignment desire, mutual action and the sum of duty satisfaction. The above result show us that the degree of wage is effected on marital status, experience of transfer, degree of satisfaction of present assignment, request of transfef and the relation between doctor and nurses is effected on experience of transfer, present assignment, degree of satisfaction of present assignment and the administration is effected on age, education, marital status position, experiences of transfer, request of transfer, degree of satisfaction of present assignment and the autonomy is effected on experience of transfer, degree of satisfaction of present assignment and the assignment desire is effected on position, pre sent assignment, degree of satisfaction of present assignment, request of transfer and the mutual action is effected on present assignment. and the sum of duty satisfaction is effected on marital status, position, experience of transfer, request of transfer, present assignment, degree of satisfaction of present assignment.

As an effective way of response evaluation in structural vibration analysis, the phase vector sum(PVS) method used in shaft torsional vibration analysis is introduced. Basic relation of PVS applicable to structural problem is derived and applied to Diesel engine structures. Concepts of forced phase vector sum (FPVS) and significance level (SL) are proposed to visualize the correlation between excitation orders and vibration modes in the SL map. The maximum responses and SL are compared and reviewed to confirm the validity of the method. It is regarded FPVS is adequate to newly evaluate the structural vibration based on excitation information.

We show how some interesting results involving series summation and the digamma function are established by means of Riemann-Liouville operator of fractional calculus. We derive the relation $$ \frac{\Gamma(\lambda)}{\Gamma(\nu)} \sum^{\infty}_{n=1}{\frac{\Gamma(\nu+n)}{n\Gamma(\lambda+n)}_{p+2}F_{p+1}(a_1, \cdots, a_{p+1},\lambda + n; x/a)} = \sum^{\infty}_{k=0}{\frac{(a_1)_k \cdots (a_{(p+1)}{(b_1)_k \cdots (b_p)_k K!} (\frac{x}{a})^k [\psi(\lambda + k) - \psi(\lambda - \nu + k)]}, Re(\lambda) > Re(\nu) \geq 0 $$ and explain some special cases.

Let X be a Tychonoff space and ${\sum}(X)$ the set of all the subrings of C(X) that contain $C^*(X)$. For any A(X) in ${\sum}(X)$ suppose $_{{\upsilon}A}X$ is the largest subspace of ${\beta}X$ containing X to which each function in A(X) can be extended continuously. Let us write A(X) ~ B(X) if and only if $_{{\upsilon}A}X=_{{\upsilon}B}X$, thereby defining an equivalence relation on ${\sum}(X)$. We have shown that an A(X) in ${\sum}(X)$ is isomorphic to C(Y ) for some space Y if and only if A(X) is the largest member of its equivalence class if and only if there exists a subspace T of ${\beta}X$ with the property that A(X)={$f{\in}C(X):f^*(p)$ is real for each $p$ in T}, $f^*$ being the unique continuous extension of $f$ in C(X) from ${\beta}X$ to $\mathbb{R}^*$, the one point compactification of $\mathbb{R}$. As a consequence it follows that if X is a realcompact space in which every $C^*$-embedded subset is closed, then C(X) is never isomorphic to any A(X) in ${\sum}(X)$ without being equal to it.
